IMG: the integrated microbial genomes database and comparative analysis system

The Integrated Microbial Genomes (IMG) system serves as a community resource for comparative analysis of publicly available genomes in a comprehensive integrated context. IMG integrates publicly available draft and complete genomes from all three domains of life with a large number of plasmids and viruses. IMG provides tools and viewers for analyzing and reviewing the annotations of genes and genomes in a comparative context. IMG's data content and analytical capabilities have been continuously extended through regular updates since its first release in March 2005. IMG is available at http: //img. jgi. doe. gov. Companion IMG systems provide support for expert review of genome annotations (IMG/ER: http: //img. jgi. doe. gov/er), teaching courses and training in microbial genome analysis (IMG/EDU: http: //img. jgi. doe. gov/edu) and analysis of genomes related to the Human Microbiome Project (IMG/HMP: http: //www. hmpdacc-resources. org/imgₕmp).
